how can I decrease the space between the text?(width)

[LT.chen]

I want to decrease the space between the sentences, but for some reasons it does not work.

are there maybe a macro  or some functions that can help me get the sentences closer to each other? or change the format to reach this? 

thank you a lot.

If you press Shift-Enter instead of just Enter, it will single-space instead of double-spacing to the next line.  Is that what you were asking about?
